Microalgae-based biofuels: advances and challenges
2023, Agroenergy: Renewable and Sustainable EnergyRecovery of vinasse with combined microalgae cultivation in a conceptual energy-efficient industrial plant: Analysis of related process considerations
2022, Renewable and Sustainable Energy ReviewsCitation Excerpt :Table 6 reports literature data on the anaerobic co-digestion of various agro-industrial and domestic wastes, and algal biomasses. Agro-industrial residues (such as vinasse) contain high C/N and alkalinity deficiency, whereas algal biomass has higher protein content, alkalinity, and pH and may present cell wall rigidity, depending on the species [23,51,130]. The co-digestion of these two substrates is a suitable option to attenuate these limitations, thereby stabilizing the AD process and increasing CH4 yield [133,148,149].
Impact of novel deflocculant ZnO/Chitosan nanocomposite film in disperser pretreatment enhancing energy efficient anaerobic digestion: Parameter assessment and cost exploration
2022, ChemosphereCitation Excerpt :Beyond 3 days, the generation methane escalated rapidly up to 13 days reached 142 mL/g COD, 182.25 mL/g COD and 230 mL/g COD for CS, FS and DS respectively. This might be due to the effective utilization of the released organic by methanogens and probable growth increment in the seed microbes (Cavinato et al., 2017). Further, increment in the duration above 13 days found stability in methane generation due to the exhaustion of released organics.
Bioremediation of lignin derivatives and phenolics in wastewater with lignin modifying enzymes: Status, opportunities and challenges
2021, Science of the Total EnvironmentCitation Excerpt :Accelerating population growth and improving natural microbial degradation, using microbes that preferably feed on contaminated sites, is a crucial feature of the bioaugmentation concept. It can be used to eliminate and alter micro-organisms, such as ethylene and chloride, that are not toxic (Cavinato et al., 2017). Natural or indigenous microbial species are usually not feasible to rapidly break down pollutants of concern.
High methane yields in anaerobic digestion of the cyanobacterium Pseudanabaena sp
2019, Algal ResearchCitation Excerpt :In contrast, methane yield reached only 226 ± 5.3 mL CH4 g−1 CODin and 215 ± 1.4 mL CH4 g−1 CODin for biomass from treatments B and C with 38 % and 61 % DW carbohydrates, respectively. Methane concentration in biogas is commonly reported around 50–70 % v v-1 [35]. Despite the differences in methane yields among Pseudanabaena biomass, methane concentration in biogas was not statistically different among treatments (p = 0.158) and contained around 61–70 % v v-1 methane for all substrates (Table 2).
